    • Sound is great!
Style: 8” 4 Ohm
The Rockville W8T4‑S4 is a solid slim subwoofer with impressive output for its size. The build feels sturdy, the cone responds cleanly, and it delivers tight, punchy bass without distortion when paired with the right amp. For a low‑profile design, it hits harder than expected and fits easily in tight spaces. Overall, a quality sub that adds real depth to a car audio setup. ... show more

I replaced the factory JBL subwoofer in a 2008 Tundra CrewMax. The factory speaker was shot. It was a 9" subwoofer, but the opening in the sub box had some play and I could screw in this Rockville sub in fine, the size was perfect. I had to line it up so that the screws would line up before I pre-drilled the holes - but that is the design of the Toyota Sub box and given it was designed for a 9" speaker not am 8". It came with foam padding on the bottom of the contact surface but I added extra. The reason I chose this is that I had a 3-1/2" height so I needed a low profile sub a this worked out great. The quality for the value was great. The JBL was light weight and not very good. The weight difference between the two was laughable. The Rockville is nice and hefty and feels durable. Now with this Rockville installed you can feel the difference. It looks great installed BUT it is facing the floor under the back seat so nobody but me (and you via my pics can appreciate it). The sound quality is great and fills out what was missing with the other speaker and amp upgrades I made. What made the install super easy was the quick attachments. I cut the wires ands stripped them and used the spring loaded wire connector to just install the wire with no issues. ... show more

Just got them one is fine the other went up. I had low power on them so im not understanding how it just went up but oh well I also purchased the warranty plan for both of them. I'm not understanding why I'm having a difficult time to get this one speaker replace. Amazon seems to not be able to replace it and rockville is making the process difficult as well. So what was the point of purchasing the warranty smmfh. I'm beyond irritated at this point with the back and forth phone calls with no results being had besides a refund no just give me another speaker wtf lol... but for the short time they both sound good on my bike ... show more

Sounds good in a ported box; however the dust cover fell off within a few weeks of use. Repaired it and it works well. Not pushing this very hard, good sound clarity.
